A GPS system has been put in place as a result of the rape and murder of 34-year-old Farah Noor Adams near the River Kelvin in Glasgow back in 2005.

The "sat-nav" lifebelts scheme now promises extra security at times of danger or emergency in the area.

Approximately 500 lifebelts have been given unique ID numbers which can be quoted to emergency services to help pinpoint the location through a control room.

Glasgow Humane Society officer George Parsonage realised that most people who were walking along the city's river banks would be unable to identify their exact whereabouts if they were attacked, involved in an accident or wanted to report an incident they witnessed.

Mr Parsonage commented: "There is a notice on the lifebelt and if you quote, for example, UN23, an orange dot starts flashing at 999 headquarters and they know exactly where you are.
